Foreword
The Environmental Protection Agency (EPA) was given a
Congressional mandate to develop criteria, standards, and
regulations governing the ocean disposal of all forms of wastes
pursuant to Public Law 92-532, the Marine Protection, Research and
Sanctuaries Act. Within this congressional mandate, EPA has
initiated a specific program to develop regulations and criteria
to control the ocean disposal of radioactive wastes.
The EPA Office of Radiation Programs (ORP) initiated
feasibility studies to determine whether current technologies
could be applied toward determining the fate of radioactive wastes
dumped in the past. After successfully locating radioactive waste
disposal containers in the disused dumpsites, ORP developed a
program of site-characterization studies to investigate (a) the
biological, geochemical and physical characteristics of these sites,
(b) the presence and distribution of radionuclides within these
sites, and (e) the performance of past packaging techniques and
materials.
These studies have provided needed information and data on
the past radioactive waste disposal activities concomitant with the
growing national and international interest in the possible long-
term effects of this low-level waste disposal option.
A key concern of EPA's ocean disposal evaluation program for
low-level radioactive waste is the potential for both mobilization
111
-------
and biological transport of released radionuclides from a dumpsite
to man. Infaunal organisms, i.e. organisms living within the
sediment, may be an important element of both of these deep-sea
processes. The present report describes the marine infauna
inhabiting the 2800m dumpsite, with a specific focus on the group
of infaunal organisms most prevalent at the site, the polychaetous
annelid worms.
The agency invites all readers of this report to send any
comments or suggestions to Mr, David E. Janes, Director, Analysis
and Support Division, Office of Radiation Programs (ANR-461),
Washington, D.C. 20460.

Abstract
Quantitative benthic samples, to collect invertebrates and
foraminifera, were taken in the summer of 1976 in the Atlantic
Ocean 2800m radioactive waste disposal site. Nine samples were
taken for invertebrates with a box core, seven of which were
located within the disposal site. A total of 86 species were
identified from a total of 353 specimens. Polychaetes constituted
approximately 50% of both the number of species and specimens.
The benthic fauna was similar at all stations, with the
polychaetes Exogone dlgpar, Langerhansia anoculata and Prionospio
steenstrnpi the most frequently encountered species. A possible
new species of serpulid polychaete was taken from the surface of
the radioactive waste barrel which had been recovered from the
dumpsite for materials analysis. All polychaetes were minute in
size, and there was no visual evidence of any large scale
biotutbation. Based on the minimal amount of downward movement of
sediments, it seems unlikely that any significant amount of
released radioactive material would become entrapped in the
sediment by biological activity.
A total of 39 species of planktonic and 45 species of
benthonic foraminifera were identified from 13 cores taken at the
Atlantic Ocean site. Unfortunately, the rose bengal solution was
extracted during the processing of samples, which made it
impossible to determine live-dead ratios. As many as 11 species
of foraminifera may represent undescribed forms.

I. INTRODUCTION
The purpose of this investigation was to determine the
benthic fauna present in and near the vicinity of the United States
Atlantic deepwater radioactive waste disposal site. Emphasis was
placed on the polychaetous annelids because of their abundance and
their role in the movement of sediments. In addition, the
foraminifera were identified, counted, and the percent of aberrant
forms recorded. The role of the benthic fauna to other forms of
animal life, especially fish, as it relates to possible
contamination from the radioactive waste material was determined
and described.
II. MATERIALS AND METHODS
Collections were made from the R/V Cape Henlopen by the
author on July 31 through August 5, 1976 during the expedition of
July 27 through August 6, 1976. The station locations, depths,
and method of collection are given in Table 1 and Figure 1. A
total of nine benthic samples were taken with a Soutar box core
*y
which sampled a surface area of approximately ,930 cm to a
variable depth of 50-80 cm. The amount of material available for
biological collection varied depending upon the needs of other
2
investigators. For most samples only about 450-500 cm of the
surface area was made available for biological analyses.
Two 2.54 cm cores were taken out of the undisturbed sample to
a depth of about 7-10 cm. The'top 5 cm was then placed within a
II rose bengal-701 ethanol solution for later foraminifera
-------
analysis. These samples were later turned over to Dr. Paul Fritts
for identification of foraminifera. The samples for foraminifera
were dried, weighed and a 100 gram subsample taken. The sediment
was then boiled with trisodium phosphate to break up the sediments
(unfortunately most of the rose bengal stain was also removed),
then washed through a 0.127 mm sieve. The material retained on
the sieve was examined under a dissecting microscope. The
foraminifera were removed for identification.
In most instances only the top 12-15 cm of sediment was
processed for macroscopic animals, by washing through a 0.5 mm
sieve. A sediment color change from tan to gray occurred at about
a depth of 12-15 cm which presumably represented approximately
that amount of sediment which had accumulated since the last
glacial age. No forms of macroscopic benthic life were present
below this depth. Only sample 14 was made completely available
for biological analysis. This sample was placed within a bucket
and a stream of sea water from a hose added; the bucket was tilted
so that the overflow passed onto the sieve. Material larger than
0.5 mm was retained on the sieve and preserved with 401 formalin.
The biological material was transported to Long Beach,
California on August 6, 1976 and washed again on a 0.25 mm sieve
to remove any remaining fine sediment and formalin. The samples
were then preserved in ethanol for later sorting and
identification.
Samples for possible biological material were taken from the
surface of the barrel raised from the dumpsite on July 31, 1976.
The sediment was preserved with 401 formalin. All sieving of
these sediments was done in Long Beach? no macroscopic animal life
-------
was present in any of this material. Several small serpulid
polychaete specimens, which possess a white calcareous tube, were
collected from the surface of the barrel and preserved (see
Columbo, et aj.., 1982, Figure 52, along lower margin of figure).
III. RESULTS
A. Invertebrates
The biological data obtained from the nine benthic samples
are summarized in Tables 2-6. Tables 2 and 3 record the species
of macroinvertebrates and foraminifera, respectively. Tables 4
and 5 record the number of species and specimens of
macroinvertebrates and foraminifera, respectively.
A total of 86 invertebrate taxa were identified of which 39
species were polychaetes, 34 were crustaceans, 7 were mollusks, 3
were echinoderms, and the remainder consisted of nematods,
sipunculids, and possibly a pogonophoran (Table 2). A total of
353 specimens were encountered of which 160 specimens were
polychaetes, 100 were crustaceans, 20 were mollusks, and the
remaining 73 specimens belonged to the nematods, echinoderms,
sipunculids, and possibly the pogonophorans. In terms of number
of specimens present, the benthos can be characterized by three
species of polychaetes: Exogone dispar (Figure 2), Langerhansia
anoculata (Figure 3), and Pripnospio gteenstrupi (Figure 4). Each
of these species was present at 8 of the 9 stations sampled with
the Soutar box corer. In spite of their widespread occurrence,
the population of these three species averaged only four specimens
or less per sample. Crustaceans, especially tanaids, and brittle
stars were often seen on the surface of the sediment in the box
-------
core, but their occurrence was limited to about 1 or 2
specimens per sample.
Two of the nine box core samples, 16 and #8, were taken
outside the radioactive waste dumpsite. No differences were noted
between these two samples and the other seven samples collected
within the dumpsite. However, many species were present only once
or twice indicating a diverse fauna but not a rich one in number
of specimens.
B.
A total of 39 planktonic species and 45 benthonic species of
forams were identified from the 13 stations in the Atlantic
survey. There were 11 additional benthonic species which were
identified only to genus since they could not be assigned to any
known species (Table 5). A total of 95 planktonic and benthonic
species were encountered from these 13 stations, of which upwards
to 11 may represent new species (Table 3). Those species of
benthonic foraminifera which could not be assigned to any
previously known species include: Alabaroina sp. , Ammpd i sgplde s
sp., gass idol ina sp. , Cjibicideg sp., Cibjcidoides sp. ,
Epistominella sp. , fraggna sp. , Rhabda^min,a sp. , Sigmoilina sp. ,
Uvigerina sp. , and Virgulina sp. . Additional study is necessary to
determine whether or not any or all of these represent new
species. The foraminiferal fauna of the 13 stations, including
the four ALVIN submersible dive stations, is fairly uniform and
the composition of the benthonic population at this 2800m
dumpsite is very similar to one described by LeRoy and
Hodgkinson (1975) from a sample taken in the Gulf of Mexico at a
depth of 1067 meters. Many of the benthonic species
-------
identified in the present study are in close agreement with those
reported by Brady (1884) from samples taken from bathyal depths on
the voyage of the H.M.S. Challenger during the years 1873-1876.
Three planktonic species, Globigerina bulloidesf G.
faIconensis, and Turborotalia jnflata were present at all 13
stations. fur bo retail a inflata and Mgo9lo..t>oquadrina pachyderm a
were numerically the most abundant planktonic species collected.
Numerically, the number of specimens of benthonic forms were
not as numerous as the planktonic species. Eiilimins; auriculata
was the only benthonic species taken from all 13 samples.
Rhabdammina abyssorum and Hoeglundina elegans were the most
#
abundant benthonic species.
No difference was noted between the species composition taken
within and outside the radioactive waste dumpsite. A few aberrant
specimens of forams were noted both within and external to the
dump site but they were of the type and percent occurrence (II) of
that which is observed from other populations of either recent or
fossil collections. Aberrant foraminifera occur in all
populations including fossil ones. When they occur, they
generally have atypical shaped chambers. The cause of aberrant
forms is unknown (Dr. Paul Fritts, personal communication).
IV. DISCUSSION
Approximately 45 percent of the invertebrate species
encountered in the Atlantic Ocean dumpsite were polychaetous
annelids. The majority of these specimens were small and were not
seen until after examination under the dissecting microscope. The
worm tubes were also minute and no burrows of any type were seen
-------
in the sediments during the processing period on board ship. The
only invertebrate species noted on board ship were the brittle
stars, tanaid crabs, isopods, a sea cucumber {holothurian}, and a sea
urchin. Jumars (1981) noted that the deep-sea benthic community
is numerically dominated by small polychaetes and nematods which
are a few millimeters or less in length, and by foraminiferans.
2
The population of invertebrates averaged about 420 specimens/m
2
or about 400/m if nematods are excluded. Comparative quantitative
data for bathyal depths are limited. Jumars and Hessler (1976)
2
reported populations of 1272 specimens/m from collections made in
the Aleutian Trench, at a depth of 7000-7500 m. Polychaetes comprised
about 49% of the specimens encountered, a figure which excluded the
nematods. Since nematods are considered as meiofauna, they are
generally excluded from population analysis of macrofauna. In the
present study, the polychaetes constituted 50% of the total specimens
collected, a figure which excluded the 30 specimens of nematods.
Most of the species of polychaetes encountered are either
detrital feeders or substrate engulfers. The detrital feeders, such
as Prionospio steenstrupi, utilize palps or other appendages to bring
material from the substratum surface to their mouths (see Fig. 4).
All syllids are provided with an eversible proboscis; benthic species
are probably elective deposit feeders and thus feed on the surface of
the sediment. Many polychaetes engulf the particle, reject the
particle or, in some species, incorporate the particle into their tube.
-------
Substratum engulfers such as Tharyx roarioni, function in much the same
manner as earthworms do on land, that is, by taking in sediment into
their digestive system, digesting at least some of the contained organic
material, and egesting the remaining material out their anus, usually at
the sediment surface. Organisms with such a type of feeding behavior may
play a role in the upward transport of sediments in the form of fecal
pellets. The population of polychaetes was sparse and the size of the
specimens was small at this dumpsite which indicates that biological
movement of sediments (bioturbation) either upward or downward may be
minimal. Further evidence for the potential lack of sediment movement
was the sharp change in sediment color at 12-15 cm, a depth easily
reached by organisms at other localities. Furthermore, microscopic
evidence failed to reveal any positively identifiable fecal pellets.
Obviously these animals were feeding, but because their size was minute
their fecal pallets were correspondingly small, suggesting minimal
vertical sediment transport potential. This lack of sediment
bioturbation in the Atlantic Ocean dumpsite would indicate that any
radioactive leakage from the barrels would tend to stay on the surface
of the sediment (or be transported away by currents) and would not be
buried, if only the bioturbation action of infauna is considered. With
the exeption of fish and an occasional sea urchin observed by personnel
within the deep submersible Alvin, no specimens present within the
sediments had a large enough biomass to permit radioactivity analysis.
-------
Biological conditions were strikedly different at the Pacific
Ocean dumpsite (Reish, in press). Many large sediment tubes and large
fecal pellets were present indicating a rich biological area. In fact,
the majority of the material retained on the 0.5 mm sieve was fecal
pellets from polychaetes. This evidence for sediment bioturbation
indicated that sediment transport is active and that any leakage of
radioactive materials would, in part, be moved vertically. Further-
more, the Pacific Ocean dumpsite would be a prime site for collection
of benthic animals for analysis of heavy metals and/or their radio-
active counterparts because of the larger sized animals and greater
population levels.
The role of polychaetes in the marine food chain is relatively
well known in shallow waters but little studied in the deep sea. In
shallow waters within the photic zone, polychaetes may be herbivores,
filter feeders, detrital feeders, carnivores, or sediment engulfers.
They, in turn, are fed upon by such invertebrates as other polychaetes,
snails, crustaceans, and echinoderms, as well as by fish. Intertidal
polychaetes are also fed upon by shore birds. Unpublished studies by
the author have shown that a single fish or bird may contain over 100
specimens of polychaetes at the time of capture. Very little is act-
ually known of the role polychaetes play in the deep sea. We can assume
that species related to shallow water forms have similar feeding habits.
The specific food habits of deep sea polychaetes have not been invest-
igated but gut contents of large specimens have been examined to a
-------
limited extent. In most instances they have fed on the sediment and
digested what organic material it contained. What feeds upon these
polychaetes is also unknown. It is likely that fish feed upon these
worms but deep-sea fish with swim bladders usually have empty stomachs
by the time they are brought to the surface since the stomach and swim
bladder evert as a result of the reduced pressure. Because of the
small size of the polychaetes in the Atlantic Ocean disposal site,
possible movement of any radioactive waste leakage from sediments to
polychaete to fish may be minor. However, because of the large size
of polychaetes in the Pacific Ocean disposal site, there may be a sig-
nificant movement of radioactive materials, in the event of a leakage,
from the sediment to the polychaete to the fish. Whether or not the
movement of radioactive material through deep-sea food chains will
reach fish harvested by man, is difficult to say. Certainly it is
more likely for the radioactive isotopes to find their way to a
commercially important organism if the isotope enters into the food
chain instead of being buried in sediments.
A list of the polychaetes previously known from off the east
coast of the United States in depths greater than 1000 meters is
given in Table 6. A total 316 different taxa have been reported
of which 201 are identified to species. It is interesting to note
that 97 of these species were described since 1965 by Hartman (1965)
and Hartman and Fauchald (1971). Only three species from the present
-------
collection were previously unknown off the Atlantic coast from depths
greater than 1000 meters: Glycera capitate is known from shallow
water off the New England coast, but it had only been reported from
oceans other than the Atlantic in depths greater than 1000 meters.
Myriowenia gosnoldi is only known previously from a collection off
New England from 97m and off Brazil in 530m. Sternapsis fossor has
been collected off the New England coast in depths up to 200m. Thanks
to the papers by Hartman (1965) and Hartman and Pauchald (1971), the
polychaete fauna in the deep water off the U.S. Atlantic coast seem
to be fairly well characterized.

18, ABSTRACT
In July-August, 1976, the U.S. Environmental Protection Agency conducted
a survey of the Atlantic low-level radioactive waste disposal site located
approximately 120 miles off the Maryland-Delaware coast at a depth of 2800
meters. Nine box core samples were collected from the dumpsite area and each
was subsampled to examine the invertebrate infauna. A total of eighty-six
invertebrate species were identified from a total of 353 specimens; only three
of the species were previously unknown off the Atlantic coast from depths
greater than 1000 meters. x Approximately 50% of both the number of species and
specimens were polychaetes, a figure which excluded the nematods,., A total of
39 species of planktonic and 45 species of benthonic foraminifera were
identified from the nine box cores plus four tube cores,, the latter having been
collected by the manned submersible ALVIN.• A discussion of the influence of
the polychaetes on possible bioturbation,of the dumpsite sediments is provided,
and a comparison is made with bioturbation potential by polychaetes in sediment
at- a low level radioactive waste dumpsite in the Pacific Ocean.
